The naturally occurring iats m ay be classified with regard to their consistency in two large groups .viz, firstly those possessing a certain plastic and pliable consistency 'which fats are forthat reason soft and moldable,

secondly those lacking in pliabilityand possessing a hard, brittle consistency as for example coooanut fat and palm kernel fat, and

' artificially hardened oils-and fats.

Ill

The fats belonging to the rfirst mentionedgroup are amongst others particularly adapted for preparing fatty products a of which a certain softness and pliability is required. The fats belonging to the second group up to now could only be used for; preparing such fatty products iftheir brittleness was reduced by addition of liquid oils. 'How-' ever, by the addition of said liquid oils the fats lose not only their brittleness but also partially their solidity as well. whereas their melting points are also-lowered. sothat they stances to the fats of said group has so "great an eflect as regards-their crystallize tion as to'materially reduce their brittleness.

According to the object one has in view with the said fats, however, a greater percentage may be added. a

To attain the purpose of the invention, unvulcanized rubber substances maybe used which are not soluble in fats. e To attain the purpose of theinvention the rubber may e dissolved in a suitableso'lvent such as ether, carbondisulfide, and thelike, and the solution added to the molten fat. 'Ihe sol vent may be reclaimed by evaporation and subsequent condensation, the rubber remaining in the fatty mass.

Example: 1,000 kg. of raw or refined palm kernel .fat are thorou hly mixed with "'a' solution of 5 kg. of rubber in' 100 kg. of

The solvent is subse 5 carbon disulphide. quently removed by evaporation.

Claims: 7 v1 v 1. The process for modifying hard brittle fats for reducing their brittleness comprising 'mixing'with the fat while in olten state a solution of rubber in a volati e sch,

and evaporating the solvent from the mixture. f
